SPINNING-RING.

Patented Oct. 22, 1907.

Application filed December 16,1902. Serial No. 135,442.

To all whom it may concern:

lie it known that 1', DAVID HARRINGTON, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful improvement in Spinning-Rings, of which the following is a specification, ac companied by drawings, forming a part of the same, in which Figure 1 represents a front elevation of the spinning ring embodying m y invention. Fig. 2 is acentral vertical sectional view, and Fig. 3 is a plan view of one half of the spinning ring holder.

Similar letters and figures of reference refer to similar parts in the different views.

My invention rela 1 es to a spinning ring provided with a track for a rotating traveler and a portion of my invention relates particularly to that class of spinning rings which are provided with a peripheral groove or track for an annular traveler.

The objects of my invention are to provide means whereby the ring will be centered automatically with the rotating bobbin during the operation of spinning; to provide a frictional. device to resist the rotation of the ring within its holder; to provide a wooden track for the rotating traveler andv protect the same from accidental injury; to enable the entire metallic portions of the ring to be stamped from sheet metal; to allow those portions of the ring to be easily replaced which are subject to wear, and to provide a simple and efficient method of securing the ring upon the rail of the spinning frame,

. and these objects, among others, I accomplish by means of the construction and arrangement of parts as hereinafter described, the novel features being pointed out in the annexed claims.

Referring to the accompanying drawings 1 denotes the ordinary ring supporting rail of a spinning frame, 2 a rotatable bobbin passing through an opening 3 in the rail. Upon the upper-surface of the rail 1 is a spinning ring holder-which consists of an annular base plate 4, resting upon the rail and provided with an interior flange 5 which overlaps the base 6 of the spinning ring. "he ring holder is held by means of three equidistant screws held in the rail concentrically with the hole 3. Two or these screws are shown at 7, 7, Fig. 1, having heads 8 which overlap the spinning ring holder and hold it in contact with the upper surface of the rail. The ring holder is provided on one side with a notch 9 slightly larger the n the screw head 8, so that when the opposite edge of the ring holder is placed beneath the heads of two of the screws, with the notch 9 in registration with the third screw, the holder will fall into place on the top of the rail without withdrawing any of the screws. By slightly turning the holder to bring its notch 9 out of registration with the screw, and tightening one of the screws, the holder will be held in position concentrically with the hole 3 in the rail.

The body of the spinning ring consists of a vertical annular metallic plate 10, provided at its lower edge with an exterior flange which forms the base 6 of the ring and rests upon the rail. Upon the outside of the plate 10 is a nonmetallic sleeve 11, preferably of wood, having its lower edge resting upon the base 6 and having its upper edge beveled at 12 and extending a short distance above the top of the plate 10. Resting upon the upper edge of the plate 10 and overlapping a shoulder 13 formed in the sleeve 11 is a nonmetallic ring 14, preferably of: wood, having at its upper edge an exterior flange 1.5 provided on its under side with a triangular rib 16 opposing the beveled surface 12 of the sleeve 11, the space between the beveled surface 12 and the rib 16 forming a peripheral groove. The exterior wall of the ring 14 is slightly tapered as at 17 and forms the bottom of the peripheral groove or track for a traveler 18, c0nsisting of a sheet metal ring provided on one side with a hook 19-to engage a yarn strand 20. Tightly fitting the upper and inner surface of the nonmetallic ring 14 is a metallic lining 21 which extends below the ring 14 as at 22, and is held by frictional contact with the interior of the metallic plate 10. An annular space 23 is left between the ring holder and the base 6 of the spinning ring, and a similar annular space 24 is left between the wooden sleeve 21 and the inner edge of the flange 5 of the holder, thereby allowing the spinning ring to be moved laterally within its ring holder. A small space 25 is also left between the upper side of the base 6 and the under side of the flange 5 of the holder, between which is inserted an annular elastic washer 26 consisting of a thin steel ring slightly warped so it will rest upon the base 6 oi the spinning ring, and at certain points bear against the under side of the flange 5 of the ring holder, in order to exert a slight frictional resistance to the rotation of the ring within the holder. The opening between the sleeve 11 and the flange 5 of the ring holder is covered by a metal cap 27, having on its inneredge an upturned flange 28 inclosing the sleeve 11 and abutting a shoulder 29 thereon. The cap 27 extends beyond the fiango 5 of the ring holder, and is provided with a downwardly turned flange 30 to prevent I the access of dirt and lint.

The ring holder 4, annular plate 10, lining 21, elastic washer 2G and cap 27 are all stamped from sheet metal by means of suitable shaped punches and dies, and the noninetallic sleeve 11 and ring 14 are preferably turned from any suitable close grained wood. The several parts of my composite ring are assembled as follows: The elastic washer 26 is applied to the body portion 10 which is placed within the ring holder; the cap 27 is placed over the flange 5 of the ring holder; the nonmetallic sleeve 11, applied to the body 10, and the metallic lining 21, with its nonmetallic ring 1.4 is then pressed into frictional contact with the inside of the body 10, thereby locking all the parts together. When the lining 21 is pressed intoplace, the lower edge of the nonmetallic ring is in contact with the upper edge of the body 10, which determines the width of the peripheral groove or track for the traveler. The triangular rib 16 limits the area of contact between the spinning ring and the upper side of the traveler and the bottom 1.7 of the track, and the upper edge 12 of the sleeve 11 are also beveled or tapering, so that the contact of the traveler with either of these surfaces is limited to a corner of the inner edge of the traveler, thereby decreasing the frictional resistance to the rotation of the traveler. The contact of the traveler with the walls of its peripheral track will cause a slow rotary movement to be imparted to the spinning ring within its ring holder. This rotary movement is retarded by the action of the elastic washer 26.

If the hook 19 of the traveler were to revolve in a path other than concentric to that part of the bobbin upon which the yarn is being wound, a varying strain or pull would be given to the yarn, but as the ring is free to move laterally within the ring holder, any variation in the pull on the yarn will cause the spinning ring to be moved laterally and restored to a concentric relation to the bobbin, thereby maintaining a uniform strain upon the yarn. The traveler 18 is provided on one side with a radial arm which is turned at right angles upwardly, inwardly, and then downwardly, nearly to the traveler to form the hook 19 having a narrow opening only to receive the yarn upon the inner side of the hook, whereby the yarn strand is prevented from disengaging itself from the hook when the tension of the yarn is removed. The space 25 between the base 6 of the ring and the flange 5 of the ring holder is sutlicient to permit a slight vertical movement to the ring within its holder, and the elastic washer 26 is preferably a very thin ring of sheet steel which is slightly warped so as to press at points of limited area against both the base 6 and flange 5 and exert'a slight and delicate pressure downward upon the base 6, and against any upward pressure of the traveler against the rib 16 of the ring due to the tension of the yarn. The delicate adjustment of the yielding pressure exerted by the elastic washer relatively to the tension of the yarn strand causes the ring to be automatically leveled by the conjoint action of these two forces, so the hook 19 will travel in a horizontal plane exactly at right angles to the axis of the rotating bobbin and thereby maintain a uniform tension on the yarn strand. The elastic washer 26 has a three-fold function; first, to retard the rotation of the ring; second, to furnish frictional resistance to the lateral movement of the ring, and third, to cooperate with the upward pull on the ring by the yarn to automatically level the ring.

I do not wish to confine myself to the precise applica tion of the yielding pressure to the ring, as shown, but I consider the thin elastic washer 26 a preferable method,

as it is extremely resilient and well adapted to exert a sensitive and delicate pressure, and as it occupies but a portion of the space between the ring and the ring holder, the clogging of the space by the accumulation of dust or lint is obviated.
